Netcat is a simple Unix utility which reads and writes data across
|
||
|
|
network connections using TCP or UDP protocol. It is designed to be a
|
||
|
|
reliable "back-end" tool that can be used directly or easily driven by
|
||
|
|
other programs and scripts. At the same time it is a feature-rich
|
||
|
|
network debugging and exploration tool, since it can create almost any
|
||
|
|
kind of connection you would need and has several interesting built-in
|
||
|
|
capabilities.
|
||
|
|
|
||
|
|
Some of netcat's major features are:
|
||
|
|
|
||
|
|
Outbound or inbound connections, TCP or UDP, to or from any ports
|
||
|
|
Full DNS forward/reverse checking, with appropriate warnings
|
||
|
|
Ability to use any local source port
|
||
|
|
Ability to use any locally-configured network source address
|
||
|
|
Built-in port-scanning capabilities, with randomizer
|
||
|
|
Built-in loose source-routing capability
|
||
|
|
Can read command line arguments from standard input
|
||
|
|
Slow-send mode, one line every N seconds
|
||
|
|
Hex dump of transmitted and received data
|
||
|
|
Optional ability to let another program service established connections
|
||
|
|
Optional telnet-options responder
|
||
